摘要

PROBLEM TO BE SOLVED: To take into consideration a human visual characteristic and to effectively remove noise by taking into consideration noise nature included in an image signal. SOLUTION: An image processing apparatus 100 for removing noise included in image data based on a parameter includes: an input terminal 110 for inputting image data; a physical characteristic value calculating part 150 for calculating a brightness-dependent physical characteristic value based on brightness of the input image data inputted from the input terminal 110; a color determining part 140 for determining a color of the image data inputted from the input terminal 110; and a parameter deciding part 160 for deciding the parameter based on the physical characteristic value calculated by the physical characteristic value calculating part 150 and a visual characteristic value according to the color determined by the color determining part 140. Consequently, noise is properly removed by the parameter determined on the basis of the physical characteristic value and the visual characteristic value. COPYRIGHT: (C)2008,JPO&INPIT
